Low Pressure Moulding

Under technical aspects Low Pressure Moulding can be classified between injection moulding and potting.

Low Pressure Moulding has obvious application-oriented advantages compared to the other applications.

With a range of 5-40 bar it is processed under considerably lower pressure and much gentler than conventional injection moulding. The pressures in this method are higher by a multiplicator of around 20-25. With Low Pressure Moulding it is therefore - contrary to the conventional injection moulding - possible without any problems to directly mould even damageable components, like for example printed boards.

In contrast to potting a clear advantage is the considerably shorter cycle time. In opposite to a more or less time-consuming hardening - possibly additionally extended by tempering - stands a relatively short cooling time. As a rule, the total cycle time of Low Pressure Moulding lies between 10 and 50 seconds.

Besides that for Low Pressure Moulding, unlike for potting, no seperate housing is required. And although the cost for hotmelt material is higher than for potting material this causes a reduction of the total costs in many
